도 1은 본 발명의 바람직한 실시예에 따른 니켈-바이퍼-디퍼지션 공정을 적용한 회전 블로우 금형의 제작공법을 개략적으로 도시한 흐름도이다.1 is a flow chart schematically showing a manufacturing method of a rotary blow mold to which a nickel-viper-deposition process according to a preferred embodiment of the present invention is applied.
도 1에 도시된 바와 같이, 본 발명에 따른 니켈-바이퍼-디퍼지션 공정을 적용한 회전 블로우 금형의 제작공법은, 성형하고자 하는 제품의 외형을 갖는 마스터 제품을 제작하는 단계(S11)와, 상기 마스터 제품의 상반부를 니켈-바이퍼-디퍼지션 (Nikel-Vapour-Deposition) 공정을 통하여 카피하는 상측 금형 카피단계(S12)와, 상기 마스터 제품의 하반부를 니켈-바이퍼-디퍼지션 공정을 통하여 카피하는 하측 금형 카피단계(S13)와, 상기 카피된 상측 금형과 하측 금형을 조립하는 단계(S14)와, 상기 조립된 금형에 분말을 장입하는 단계(S15) 및 상기 분말이 장입된 금형을 회전과 동시에 열을 가하여 분말의 적층으로 상기 마스터 제품의 외형을 갖는 제품을 성형하는 단계(S16)로 이루어진다.As shown in Figure 1, the manufacturing method of the rotary blow mold applying the nickel-viper-deposition process according to the present invention, the step of producing a master product having the appearance of the product to be molded (S11), and The upper mold copy step (S12) for copying the upper half of the master product through the nickel-vapour-deposition process, and the lower half of the master product through the nickel-viper-deposition process. A lower mold copying step (S13), and assembling the copied upper and lower molds (S14), loading powder into the assembled mold (S15) and rotating the mold into which the powder is loaded. Simultaneously applying heat to form a product having the appearance of the master product by lamination of the powder is made (S16).
상기 마스터 제품을 제작하는 단계(S11)는 성형하고자 하는 제품의 외관을 갖는 제품을 제작하는 단계를 말한다.Producing the master product (S11) refers to the step of producing a product having the appearance of the product to be molded.
상기 상측 금형 카피단계(S12)는 니켈-바이퍼-디퍼지션 공정을 적용하여 마스터 제품의 상반부를 카피한다. 상기 니켈-바이퍼-디퍼지션 공정은 기상(氣相)으로부터 금속을 타출해 내는 원리에 기초한 금속 정연 공정으로서, 니켈 부품형을 단기간에 제작가능 하게 하며 성형 두께에 유연하게 적용 가능한 공정을 말한다.The upper mold copy step S12 copies the upper half of the master product by applying a nickel-viper-deposition process. The nickel-viper-deposition process is a metal refining process based on the principle of extracting metal from the gas phase, and refers to a process that enables a nickel component mold to be manufactured in a short time and is flexibly applied to the molding thickness.
그리고 상기 하측 금형 카피단계(S13)는 마스터 제품의 하반부를 카피하는 단계()를 말하는 것으로서, 니켈-바이퍼-디퍼지션 공정이 동일하게 적용된다.And the lower mold copy step (S13) refers to the step of copying the lower half of the master product (), the nickel-viper-deposition process is equally applied.

다음, 상기 일체로 조립된 금형에는 플라스틱 분말이 장입되고(S15), 이 조립된 금형에는 열이 가하여 짐과 동시에 회전되어 제품이 성형된다.(S16) 즉, 소정의 오븐에 플라스틱 분말이 장입된 상기 금형이 들어가 오븐내에서 반복 회전된다. 그러면, 금형의 내부에서 분말이 녹으면서 계속적으로 적층되어, 마스터 제품과 동일한 외관을 갖는 제품이 성형된다. 이에 따라, 분말의 적층에 의하여 제품이 성형됨으로써, 복잡한 형상의 성형이 가능하고, 니켈을 이용한 니켈-바이퍼-디퍼지션 공정을 통한 금형의 제작으로 열전도성이 좋아 작업 효율이 상승되는 구조를 갖는다.Next, plastic powder is charged into the integrated mold (S15), and the assembled mold is heated and simultaneously rotated to form a product. (S16) That is, the plastic powder is charged into a predetermined oven. The mold enters and is repeatedly rotated in the oven. Then, the powder is continuously laminated while the powder melts, and a product having the same appearance as the master product is molded. As a result, the product is molded by lamination of powder, so that a complicated shape can be formed, and a structure having a good thermal conductivity is improved by manufacturing a mold through a nickel-viper-deposition process using nickel. .
